cleats, from which a fol'dable bxblank of desired dimensions may .beproduced by the assembly of the required number of individual sections,the assembly` resulting in a stiffening or reinforcement oftheAlongitudinal corners of the completed box.

The accompanying drawings illustrate my invention. Figure l1 isha`perspective view of the completed box; Fig. 2 a trans verse section, ina plane' parallel witliwth'e removable ends, the end sheetbeing'b'rb'lt'en away at its corners to show the relation of the severalcleats; Fig. 3 a plan of a series of four separate sections 'prior totheir 'assemblage in foldablelblan'k form; Fig. 4 'a similar viewshowing the 'sections fastened together and one series of cleats turiiedup into foldable relationship; Fig, 5 a section, on a larger scale, online 5, 5 vof Fig. 4E; Fig. 6 a perspectivevvi'ew of a slightl rhodrfiedl form of completed pacl'gage, tje portions of the sheets being'broken away yto show parts which would bel-otherwise hidden; Fig. 7 afragmentary section o'f the modification shown in Fig. 6; and Fig. 8 aplan of a slightly modified boX-for'mii'ig section embodying myinvention. y

In the drawings, 10 indicates the main sheet of one of my boX sectionsof 'material which is capable of being bent along desired fold lines,-such, for instance, as ber board, corrugated board, other lsuitablepaper products, etc. The size of each sheet 10 will be determined by thedimensions of the boX desired and at each side edge it will be providedwith a flap 11, a fold line 12 being formed, by scoring, pressing orotherwise, to facilitate, if that is necessary, the folding of the aps11 to positions at an angle to sheet 10. Two cleats 13, 13 are attachedto sheet 10 in such manner that, when several sections are broughttogether and foldeda the said cleats will interengage P rammed4inependenuyend may, therefore,

lThe to bottom and side seetio'ns are be /produeeajin steek dimensioneso that 'by zpiroper selection ofseoek Steenen-S, boxes of any standarddniensions may 'be produced.

'The several 'sectionsere brought together 'in the meneer ehownin Fig.

v i the body sheets l0 and flaps 11 beingoverlipp'ed, as indicated, andthe ten'allyelyin'g jfiapsll are attached 'to the body sheets "of theadjacent {eeeions'n eeysuitable manner. The? may f I astenner' iyiii'gepe n my ele@ be eaeehea te the main body 'ofthe 'adjacent section, ,butiiithatcase special scoring at the'fold linev `ofthe intern-aligning Hap11 muet be resorted to in or-'dier to compensate for the thickness ofthe material 'at'the -fold line or corner of the completed package.

The production of the individual boxforming se'etiois considerablyfacilitates... manufacture and ultimate production of packages ofvarious sizes, and the overlap# ping of the Haps l1 upon the adjacentbodies l0 produces a double thickness 0f material at the longitudinaledges 0f the package between the cleat planes, thus materially stileningthe package in lines at right angles to the end planes not only againstthrusts along those lines, but also against tearing' stresses presu,tiiig af. 'rabkiu'g of the package. 'j A f Any suitable form of ends maybe used and in the drawings'fI have shown an end consisting of a sheet20 of the same material as the body members, provided with a pair :oftransverse cleats 2l, each having' t'ongl'ies'` 22at their'ends; saidtongu'espro'-4 jecting into mortises 23Lformed; in the cleats 13 of theside members, saidmortises being suiiiciently deepened-foixthat urpose.

By making those iiaps v:11. W iich lie With,- in the packa e of suicientlength to .be overlaid by the c eats when said cleats are folded intoblank-folding position, as indicated at the right ofyFig. 5the cleatsserve to hold the ends of said interior fiaps 11 firmly in place andthis serves to' assist in the stijiening eiiect ofthese fia-ps upon thebox corner.

n the form shown in Fig. 8, -the end {ia-ps 14 areomitted and the cleats13 are applied directly to the main bod sheet 10. In this form, the sideflaps 111W ich are intendedto lie Within the package, must be made shortenough-to lie between the cleats when the partsare brought together inbox blank arrangement.

The top section will, of course, :have a side iap alongthat edge whichforms the free edge Aof the cover.' This final flap, 11 may lie outsideof the adjacent side member, as shown in Fig. 1, being attached theretoby any suitable means to hold the box closed, but for somepackages itwill be advisable to protectthis flap, 4and for that purposea strip 25may be applied to the outer faceat the top edge of the front section sovas to form a pocket 26 .for the reception of the flap 11a (Fig. 6), theila 11 at the top ofthe fronts section exten ing horizontally beneaththemain body ofthe top section -when the top is folded into closedposition. =Instead of using the strip 25, a pocket for the flap 11L maybe formed in the manner shown 1n- Fig. 7, a strip 27 bein applied to theinner face of the sheet 10 o the front member of the box. In .this case,the upper edge of this front member will not be provided With any edgeflap,

but, instead, the strip 27 will be of such Width as to extend beyond theedge of said sheet 10, thus forming a iiap 28 whichl will extend beneaththe -main body of the top section.

I claim, as my invention r' 1. A foldable box blank comprising aplurality of individual sections, each formed of exible sheet materialand transverse cleats, each of said sections having edge flapsoverlapping the body sheet of an adjacent section, and one of saidoverlapping flaps adjacent each fold line being secured tothevoverlapped body.

2. A foldable box blank comprising a plurality of sections, each sectioncomprising a main body sheet, edge flaps overlapping the main body sheetof an adjacent section, oneedge flap at each fold line being attached tothe adjacent body sheet, end iaps foldable with relation to the bodysheet, and cleats attached to said end flaps and extending transverselywith relation to the side flaps.

3. Asan article of manufacture, a box blank section comprising a mainbodysheet of. iiexible material having side flaps foldahlewith relationto the body sheet, andA also having end iaps foldable with relation tothe body sheet, and cleats attached to said end flaps.

4:. 4A foldable box blank comprising a plurality of sections, eachsection comprising amain Abody sheet, edge flaps overlapping the mainbody sheet of an adjacent section, one edge Hap at each fold line beingattached to the adjacent body sheet, end flaps foldable with relation tothe body sheet, cleats attached tosaid end flaps and extendingtransversely with relation to the side' iiaps, and a flap-receivingpocket can ried by one of the terminal sections of the blank to receivethe side flap of the free edge of the other terminal section.

5, A foldable box blank comprising a plurality of body sections, eachsection comprising a main portion and edge flaps foldable relative tothe main body and an edge Hap at each-fold line overlapping an adjacentbody sheet and attached thereto, and cleatsI attached to said bodysheets in posi tion to coperate in series when the blank is folded intobox form.

In witness whereof, I have hereunto set my hand at Indianapolis,Indiana, this thirteenth day of December, A. I). one thousand ninehundred and fifteen.
